Information × Registration Number 0213U007586, 0113U002865 , R & D reports Title Implementation of an installation prototype of uranium supercritical extraction for the recultivation of waste of the nuclear enterprises popup.stage_title Head Tkachenko Viktor Ivanovych, Registration Date 24-12-2013 Organization National Science Center "Kharkiv Institute of Physics and Technology popup.description2 The main chemical reagents have been listed for carrying out sample preparation, and founded their characteristics. Chosen minerals for the simulation of tailings material with a relative ratio of uranium: № 1 (Basalt) : № 2 (Descent Passionarians) : № 3 (Red granite) = 1,0 : 7,5 : 3,6, which allows them to simulate the tailings material in a wide range of uranium content. Sample preparation has been described as a multistage process, in which are stages: grinding, receiving uranium complex, which effectively extracted by supercritical carbon dioxide and separation of organic fraction, which contains the entire uranium complex. The method has been described for controlling output samples for the uranium content on a spectrophotometer SP - 2000, which is necessary at all stages of sample preparation process.
